Django Admin Kink with Collapse Fieldsets
我无法在管理控件中显示collapse字段集。最重要的是，每当我进入管理控件时，我偶尔也会出现加载错误，这似乎只是出现了。我不能把这些错误拼凑起来猜测导致问题的原因，但是当我在admin.py中包含所包含的代码时，我似乎只能重现它。
管理员布局错误
admin.py
from forum.models import Category, Thread, Post
from django.contrib import admin
class PostAdmin(admin.ModelAdmin):
fieldsets = [
(None, {'fields': ['author']}),
(None, {'fields': ['thread']}),
(None, {'fields': ['creation_date']}),
(None, {'fields': ['content'], 'classes': ['collapse']}),
(None, {'fields': ['is_removed']}),
(None, {'fields': ['agrees'], 'classes': ['collapse']}),
(None, {'fields': ['thanks'], 'classes': ['collapse']}),
(None, {'fields': ['saves'], 'classes': ['collapse']}),
]
admin.site.register(Post, PostAdmin)
（偶尔）错误

任何可能导致此问题的想法？
编辑： 经过仔细审核后，即使折叠的字段被注释掉，错误仍然存在。布局问题可能与此错误有关或完全分开。我希望看到两者都固定，显然。
这是一个看似不同的错误：

问题是这个（和类似的）行：
(None, {'fields': ['agrees'], 'classes': ['collapse']}),
当字段集标题为None时，没有字段集标题，因此无需单击以展开字段集。 Django错误跟踪器中的This comment，虽然陈旧，但表示不使用标题和collapse是一个坏主意（tm）而你“不应该这样做。”
至于您的其他问题，您的操作系统存在某种形式的问题。它只是意味着建立了一个连接（到你的Python服务器），但你的计算机（你的主机）在Python完成它之前终止了连接。
这个问题有点陈旧但是对于像“django fieldset collapse不起作用”这样的搜索结果仍然相当高，所以我想我可能会为未来的搜索者回答它。
